> For any other conceivable use case, a database and a contract between parties are a superior solution. Except when banks are transferring money across borders. In order to have trust, they currently need what's called nostro and vostro accounts. Meaning, Bank A parks money in Bank B, and Bank B parks money in Bank A. So that if a transfer is fraudulent, there will be money to cover it. How is that better than blockchain?
